feat(authz): enable FGA for telemetry resources (#12095)
* feat(authz): enable FGA for telemetry resources on v5 query_range

Authorize /api/v5/query_range and /preview at the telemetry-resource level,
derived from the request body:

- coretypes: ResourceWithID + ResourceExtractor as the resource-level analogue
  of the id extractors; NewResolvedResourceWithID/NewResolvedResourceWithError;
  telemetryresource selector regex widened to query-type selectors with up to
  two hashed segments (metric name, where clause) or wildcards
- telemetrytypes: QueryRangeResources maps each query to its telemetry
  resource (signal/source aware: audit-logs, meter-metrics) with a hierarchical
  selector id (query_type/<hash(metric)>/<hash(where)>); PrefixSelector expands
  the id into the grant ladder [exact, prefix/*..., *]
- handler: generic TelemetryResourceDef fans out an injected ResourceExtractor;
  fails closed when extraction errors or resolves nothing
- audit: log and skip resolved resources that carry a resolution error
- querier routes: ViewAccess -> CheckResources with telemetry read scopes;
  substitute_vars stays ViewAccess (no telemetry access)
- sqlmigration 099: backfill telemetry read tuples for existing orgs
  (admin: logs/traces/metrics/audit-logs/meter-metrics; editor/viewer:
  logs/traces/metrics)

* feat(authz): widen telemetry selector segments to 128 bits

64-bit truncation permits chosen-collision attacks at ~2^32 work; 128 bits
pushes this to 2^64. No hashed selector is persisted yet, so the change is
free.

* chore(docs): regenerate openapi spec with telemetry read scopes

* feat(telemetry): add where clause visitor

* refactor(telemetry): restructure normalizer file and quote bare values

* feat(authz): gate v5 query_range on service.name telemetry selectors

* feat(authz): encode telemetry grants as query-type qualified atom selectors

* feat(authz): move telemetry grant key to plaintext selector segment

* feat(authz): use escaped plaintext telemetry selectors with mechanical ladder

* revert(authz): restore transaction group diff in role update

* test(authz): add querierauthz integration suite for telemetry query_range gating

* test(authz): seed logs so service.name resolves in allowed querierauthz cases

* feat(authz): backfill telemetry read tuples for existing orgs

* chore(authz): reword empty composite query error message

* feat(authz): add meter metrics and audit logs to clickhouse sql

* Revert "feat(authz): add meter metrics and audit logs to clickhouse sql"

This reverts commit c9d870e0ee.

* feat(authz): grant meter-metrics to editor/viewer, keep clickhouse admin-only

* feat(authz): remove the audit logs from clickhouse check altogether until it's introduced
